Already they have been organising little fundraisers along the way including a "crazy sock day" at their former school on February 23.

Elki posted a video in her own crazy socks to say thanks after more than $1000 was raised.

Bonnie and Emelie have now set their sights on making a big difference and aim to raise $5000 when they join in the World's Greatest Shave for Elki on March 17.

The shave will be happening in assembly at Nambour State College.

Anyone who would like to help them achieve this target and help Elki and her family can make donations to a bank account set up for the cause The BSB: 124090; Account number: 22499077; Account name: Emelie Orrell or visit their Facebook page, Em&Bon - World's Greatest Shave.
